Mesclun lettuce is simply a mixture of different types of leaf lettuce. There are many varieties. Usually it matures at a rate that you can't use it all up in salads. Last night I tried to use it as a vegetable and it was very good. Great way to use that extra lettuce. I would also try other lettuces with some watercress mixed in. Serve this like you would spinach as a veggie side dish Do Not overcook it only takes about 4 minutes. Usually the water on the leaves is enough moisture but if it is dry add a couple tablespoons of water to the pan. Notice in the picture that I have added some pecans - Use your own imagination.
